Application of Inverted Arch Core Detection Technology in Tunnels
The detection of the Inverted arch core is a kind of damage detection method.At the top of the Inverted arch and structure layers of the construction formation,Use a portable wire removal machine and other equipment,Drill the concrete core sample from top to bottom,and sort the core samples in order of drilling.The core sample can intuitively reflect the thickness and denseness of the concrete of the elevation and filling layer(structural layer).The detection of Inverted arch core can be used for quality testing,completion acceptance testing,and maintenance detection in tunnel operations during the tunnel construction.
